Hiding item in DataGrid

[David C]

I have a DataGrid that displays 3 columns from a list of Files in a
Directory. The first column is a HyperLink that displays the file name with
a link to another page and querystring. Below is the DataGrid and below
that is the ItemDataBound code that is not hiding the file named
"Thumbs.db". What am I doing wrong to hide that cell? p.s. I would prefer to
hide the whole row. Thanks.

    Protected Sub articleList_ItemDataBound(ByVal sender As Object, ByVal e

articleList.ItemDataBound
        If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType =
ListItemType.AlternatingItem Then
            Dim hlcol As HyperLinkColumn = articleList.Columns(0)
            Dim value As String

            value = hlcol.DataNavigateUrlFormatString.ToString()
            If value = "ShowDocs.aspx?doc=Thumbs.db" Then
                e.Item.Cells(0).Visible = False
            End If

    End Sub

are you sure that this is correct?
If value = "ShowDocs.aspx?doc=Thumbs.db" Then

To hide the whole row you need to set

for (int i = 0; i < e.Item.Cells.Count; i++)
e.Item.Cells.Visible = true;
